MBRF1090CT

Diode Arrays Overview

The MBRF1090CT is a dual common-cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a 10 A average forward current rating and a 90 V repetitive peak reverse voltage. The device utilizes an ITO-220AB package with a junction temperature range of -55°C to +150°C. Electrical specifications include a typical forward voltage of 0.85 V at 5 A and 0.95 V at 10 A, alongside a maximum surge current capability of 120 A.

Diode Arrays Feature Summary

• Guard ring structure provides protection against overvoltage stress
• High efficiency operation resulting from low power loss characteristics
• Robust high surge current capability for transient handling

Diode Arrays Applications

• Switching mode power supplies (SMPS)
• DC to DC converters
• Adapters

Diode Arrays Procurement Notes

Verify the specific ordering code suffix when sourcing components. The standard 'MBRF1090CT' designation indicates general production units, while the 'H' suffix denotes AEC-Q101 qualified automotive-grade devices. Confirm the exact suffix required for your supply chain needs to ensure compliance with quality standards.

Diode Arrays Selection Notes

Select this component for circuits requiring a 90 V reverse voltage blocking capability with a 10 A continuous current load. The ITO-220AB package facilitates heatsink mounting for thermal management. Ensure the application operates within the specified 150°C junction temperature limit and accounts for the 3.5 °C/W thermal resistance.

Diode Arrays Part Context

This part belongs to the MBRF10xCT series, which covers voltage ratings from 35 V to 200 V. All members share identical current ratings and packaging but differ in reverse voltage specifications. The series is designed for high-frequency rectification applications where low forward voltage drop is critical for system efficiency.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers offering 10 A, 90 V Schottky rectifiers in the ITO-220AB or TO-220AB package. Verify that substitute parts meet the same electrical parameters, specifically the 120 A surge current rating and 150°C maximum junction temperature.
